March 5, 1940. s. F. GLEASON MEAT MOLDING AND PROCESSING DEVICE 1 Filed Nov. 14, 1938 2 Sheets-Sheet 2 INVENTOR STE UIE ED522212 OFSRNEY Patented Mar. 5, 1940 UNITED STATES PATENT OFFlCE 6 Claims.

. My invention relates to a new and useful meat processing and. molding device of the type employed in the packing industry for cooking, molding or otherwise treating or processing boned meats such as hams, shoulders, picnics, and

. tenance in cleaning, is reduced, and whereby the device as a whole will be in strict conformity with such laws as are provided for regulating, packing and processing; of meats.

. Myinvention still further relates to a device of this character by means of which equalized and constantly self-equalizing pressure is automatically applied to the meat or meat product being processed without the necessity of any subsequent tension, variation or adjustment once the meat product has been placed in the device and the device has been closed in the proper manner.

.1 My invention still further relates to a meat processingfdevice in which guides are provided for, the springs exerting the pressure on the cover orifollowing member to prevent longitudinal displacement of the springs thus guarding against any possible inequality in the pressure exerted, and in which, for the same purpose, other guide means are provided for preventing tilting or' vertical displacement of the cover or following member under tension of the pressure-applying v springs, whereby a constantly uniform and selfequalizing following pressure is exerted upon the initially, irregular or non-uniform mass of meat placed in the device, so that, asthe meat is processed and softened, it is forced into a uniform and homogeneous mass conforming to the shape and contour of the device.

'My invention still further relates to a meat cooking device which, for practical purposes, is formed of what may be termed as two units, one unit being the container for reception of the meat to be treated and the other unit comprising an integrated assembly of the following member, the cover, the" pressure-exerting springs and the clamping or retaining members, said mechanism being adapted for automatic application by a single operation,

' Other features of novelty and construction will be more clearly'understood from the following specification and the accompanying drawings in i h; i

' Fig. 1 represents a side elevation partly in section of a meat processing device embodying my invention, the same being shown in open position, that'is, before it is clamped down upon the meat therein.

Fig. 2 represents a view similar to Fig. 1 showingv the device as having been compressed, with the meat in proper position.

Fig. 3 represents a section on line 3-3 of Fig. 1.

Referring to the drawings in which like reference characters indicate like parts, and more particularly to Fig. 1, my novel meat processing and molding device comprises a container 1 of the desired dimensions and shape adapted to receive the meat to be treated 2. As shown in the drawings the meat is represented-as being a ham, but it is to be understood that any other boned meat or meat product can be treated if desired. The container 'i is provided with the peripheral flange or turned-down rim 3 which is adapted to be engaged by the coacting ratchets 4. The ratchets are pivoted at 5 to the cross bar or supporting member 6. "l designates a cover or follower plate which contacts the meat being processed and which is provided on its upper surface with the guiding and stiffening channel 8. The channel 3 may be suitably. secured to the cover l by any suitable means such as spot-welding, riveting, or the like. iii and l l designate oppositely deflected flat springs which are united about their center by the clip i2 with the opposite ends of the lower spring ll guided in the channel 8 and slidably bearing against the top of the cover l. The opposite ends of the upper spring iii are similarly guided in the pockets or channels l3 formed on the underside of the cross bar 5, it being understood that the ends of the upper spring ID are slidable within the channels. or pockets l3 along the under surface of the cross bar ii. In the center of the cover 7 and preferably extruded integrally from the channel member 8 is formed the hub 14 into which is threadedly or otherwise secured the guide pin l5 which passes through an opening "5 in the spring clip E2. The pin l5 may be suitably locked in place by the lock nut I! or the like. The upper end of the guide pin I5 is provided with a shoulder l8 which, by engaging the bottom shoulder ill of the sleeve 20, limits the downward movement of the guide pin l5. By

this means the maximum expansion of the springs is limited to a predetermined position in l which the springs i0 and H are always in constant engagement under partial tension. The sleeve 20 is threaded or otherwise secured in the hub 2| formed in the cross bar ii and it is retained in place by the lock nut 22 or the like which also serves as an upper stop to limit the upper movement of the pin l5 and thus limit the maximum compression of the spring or closure of the device to guard against undue compression of the spring which may result in damage thereto.

The operation is as follows:

which, in most cases, is of a non-uniform or irregular shape, is placed in the container l and with the ratchets 4 disengaged from the rim or flange 3 the cover plate 1 is positioned over the meat 2 and the preassembled, pressure-applying assembly is placed in position with the cover 1 resting upon the meat 2. Pressure is then applied upon the cross bar 6 thus compressing the springs l and H and bringing the ratchets 4 downwardly into engagement with the flange or rim 3 as shown in Fig, 2. When engaging the ratchets 4 with the flange 3, it is important to have the corresponding teeth of the opposite ratchets engaging the adjacent portion of the rim or flange 3. By this uniform compression of the springs I [I and l I over the initial nonuniform meat 2 placed in the container, more pressure is exerted upon the butt end of the meat than on the thin shank thereof, so that,'as the meat softens during the processing thereof, the mass of said meat is displaced gradually until it is a uniform, homogeneous mass conforming to the contour of the container l In order to insure against the tendency of the cover or follower member 1 to tilt or beinclined, horizontally speaking, due to the presence under one end thereof of the relatively thick, nonyielding butt end of the meat while the shank of the meat is under the opposite end of the following member I I have provided the guide pin l5 which passes throughthe spring clip l2 which insures a constant horizontal position of the follower plate 1 during the entire processing operation.

It will be noted that the following pressure exerted by the springs I 0 and II is continuous throughout the processing operation by which i is meant, not only the heat treatment for cooking and processing the meat but also the step of chilling the meat and its congealing after the cooking process proper has been completed.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
